Rio de Janeiro’s famed Carnival will be held in late April rather than the final weekend of February, as the number of coronavirus cases in Brazil spikes and the omicron variant spreads across the country.

“The decision was made respecting for the current situation of the COVID-19 pandemic in Brazil and the need, at this time, to preserve lives and join forces to drive vaccination throughout the country,” said a statement issued jointly by the cities of Rio and Sao Paulo, which also delayed the start of its Carnival parades until April 21.

Rio’s Mayor Eduardo Paes announced weeks ago that his city’s raucous street parties, some of which draw hundreds of thousands of revellers, wouldn’t proceed in the manner they did before the pandemic, but without clarifying what shape they might take.

He said at the time, however, that samba schools’ parades through the Sambadrome would proceed as planned, in light of the relative ease with which vaccination status and negative coronavirus tests could be checked upon entry.

The parade through the Sambadrome is a major tourist draw for Rio and the central fixture of the city’s pre-Lenten party. It draws tens of thousands of spectators in its bleachers and tens of millions watch from home.
